Thank you AlexZtuned for the video of your S4, Motortrend for your video of
AMS's GT-R, and deadmau5 for the killer audio.
Alex's S4 is now running on e85 and is even faster. AMS now offers a Alpha 10 package,
and soon BoostPatrol.com will have
some cars of it's own to compete.

The Beast is Back - ARD Audi S4 puts down 591 WHP on E85!
The beast is back! See how the new setup performs on the Dyno with E85:
- Twin GT28RS turbochargers with 68mm FP
HTA compressor wheels
- 4'' custom Exhaust
- Fuel Lab 1300HP external pump
- 1000cc EV14 injectors
- Tilton twin disk clutch.
The S4 now puts down 591whp at just 28 psi tapering to 24 psi on a baseline
file without any water/meth injection activated. Wonder what it will do at
30+ psi? Stay tuned for more videos!
